“He who indulges, bulges” is a jocular food saying that has been printed on several gift items. Eleanor S. J. Rydberg first wrote the line for The Saturday Evening Post, published on October 8, 1955.
     
The “Dear Abby” advice column used the line in 1958 and 1964. Beverly Hills nutritionist-to-the-stars and “dietary drill sergeant” Hermien Lee (1917-2009) also used the line, but didn’t coin it.

Hermien Lee, no-nonsense nutritionist to the stars, dies at 92
Sometimes called a ‘food Nazi’ and a ‘dietary drill sergeant,’ she also offered 14-week courses to businessmen, housewives and children about losing weight and eating right.
June 27, 2009 | Jon Thurber
Hermien M. Lee, a Beverly Hills nutritionist who taught her no-nonsense approach to eating right to a variety of stars including Ann-Margret, Joan Lunden, Suzanne Somers and Robert Wagner, has died. She was 92.
(...)
She moved to Southern California in the 1970s and began preaching her mealtime mantras. Her book “The Spot Reducing Diet” was published in 1983. Her conversation was dotted with favorite phrases like: “He who indulges, bulges,” she told a Times reporter in 2001. “He who stuffeth, puffeth.”
